Recent linguistic landscape (LL) research has witnessed a change in focus to untypical, peripheral and fluid signs. Compared to typical (or permanent, fixed, etc.) signs which tend to be subject to strong policy intervention, language use on untypical signs is often more autonomous, thus could better reflect the "de facto" language choice and preferences of local residents. Comparing the linguistic patterns between typical and untypical signs therefore provides a way to investigate the tension between mandated language policies and residents' language choice. In this study, we adopted the dichotomous terms proposed by Shang, G., and X. Zhou. 2020. "[foreign characters omitted] [Peripheral Linguistic Landscape: Sign Types, Features and Research Perspectives]." [foreign characters omitted] 5 (4): 37-47., namely 'typical' and 'peripheral', to explore the language use on public signs in Kashgar, Xinjiang Uyghur Autonomous Region, China. By comparing typical and peripheral signs in Kashgar, the study found a significant discrepancy: Chinese is prioritised on typical signs due to top-down policy promotion, while Uyghur is used extensively on peripheral signs by local residents. This study demonstrates the importance of analysing peripheral linguistic landscape in strong-policy nations/regions.
